"When dinosaurs ruled the Earth, we tend to think of the mammals at the time — including our distant ancestors — as small and quivering in the shadows. "We've always had this picture of mammals as the literal underdogs," says Elsa Panciroli, a paleontologist at the Oxford University Museum of Natural History. "They're being trampled. They're cowering in the darkness at night, just trying to avoid being eaten." But a remarkable new fossil, originating in the early Cretaceous some 125 million years ago and now described in the journal Scientific Reports, conjures a rather different possibility. It consists of two intertwined skeletons — an upstart mammal sinking its teeth into a much larger dinosaur. "Our best guess is that the mammal was in the middle of attacking the dinosaur," says Jordan Mallon, one of the authors of the new study and a paleobiologist at the Canadian Museum of Nature. If true, such a revelation shakes our traditional view of dinosaur domination and mammal submission. It suggests a more complex ancient food web in which certain dinosaurs were prey and some mammals were predators. In the case of this particular fossil that was unearthed in modern-day northeast China, "this mammal appears to have been particularly gutsy or voracious," Mallon says."

Rickey Repenomamus 

071/365 #hunt the repenomamus

Had no idea what that was, but upon researching I found out it's sort of a prehistoric oddity- a mammal that hunted dinosaurs, as they found the smaller skeleton of a dinosaur inside of its stomach. It doesn't seem to have modern-day predecessors but it's been compared to opossums and badgers. I included a Sabretooth Pete too because I had some space and it helped ground it a bit more in the prehistoric setting I was looking for.

I am making 365 new versions of Mickey Mouse for the public domain and releasing them under public domain all year long.

I haven't posted any PBS Eons commissions here for quite a while, so let's catch up a bit of the backlog:

• The Cretaceous mammals Repenomamus robustus and Repenomamus giganticus, from "When Mammals Only Went Out At Night" https://www.youtube.com/watch?v=JqZONKXWPfw

• A carcass of the whale Borealodon, from "How Ancient Whales May Have Changed the Deep Ocean" https://www.youtube.com/watch?v=1vb00-gcdtA

• And the early vertebrates Haikouichthys and Myllokunmingia, from "Why Sour May Be The Oldest Taste" https://www.youtube.com/watch?v=XXgd_cNZSvk

Jurassic June day 20

Repenomamus

Done for the book “Traumreise In Die Urzeit” by Markus Peter Kretschmer.

One of the largest known mammals from the Mesozoic, there’s direct evidence that it fed on dinosaurs. And since it’s basically an ancestor of all modern mammals, and is rather rodent-like, if just in appearance, it could be argued that it’s an ancient rat. So it’s pretty much a dinosaur eating rat! 😆

(You can “Um, achktually…” comment all you want. I don’t care)

A Predation or Scavenging Scene?

Among the fossils that are all the rage these days is the famous “gigantic” Repenomamus Cretaceous mammal entangled with a Psittacosaurus, in what is apparently a battle to the death… rivaling the famous Velociraptor and Protoceratops battle from the Gobi desert. However, it has also been proposed that we are seeing a mammal famous for having bones of little psittacosaurs in its belly in some of…

A remarkably well-preserved fossil discovered in China suggests that millions of years ago, some mammals actively hunted dinosaurs that were several times their size. The 125-million-year-old bones, uncovered in 2012, consist of a cat-sized creature called Repenomamus robustus, whose skeleton is entangled in a final tussle with a beaked dinosaur known as Psittacosaurus lujiatunensis. The two animals’ fight was immortalized when a nearby volcanic eruption entombed them in a fast-moving wave of ash and mud.

An article published in the journal "Scientific Reports" describes what appears to all intents and purposes a fight in which a mammal of the species Repenomamus robustus attacked a dinosaur of the species Psittacosaurus lujiatunensis. A team of researchers examined fossils discovered in today's China dating back to about 125 million years ago, in the Jurassic period, which offer the first evidence of a mammal hunting a dinosaur. The two animals engaged in a mortal fight became entangled in a flow of volcanic mud similar to the one called lahar in jargon, leaving evidence of that fight.

Although most Mesozoic mammals were rather small, a few different lineages produced some pretty hefty-sized forms – most notably the metatherian Didelphodon, the gondwantherians Adalatherium and Vintana, and the eutriconodont Repenomamus.

And now we've got another one to add to that list.

Patagomaia chainko lived towards the end of the Cretaceous, about 70 million years ago, in what is now Patagonia near the southern tip of South America. Known from some partial leg and hip bones, it was potentially the largest known Mesozoic mammal yet discovered – estimated to have been similar in size to a modern bobcat, roughly 50cm tall at the shoulder (~1'8") and weighing around 14kg (~31lbs).

Distinctive anatomical features of the bones indicate it was an early therian mammal, the group that contains both modern marsupials and placentals, but it can't currently be classified any more specifically than that. Mesozoic therian fossils are very rare in the southern continents, so Patagomaia's presence in late Cretaceous South America adds to their known range and diversity, as well as providing an example of surprisingly large body size for the time.

Without more material it's impossible to tell what Patagomaia's ecology was. I've gone for a fairly generic life appearance here, and while what's known of its joints and muscle attachments doesn't indicate climbing specializations, plenty of unexpected tetrapods still like to get up on tree branches.
